Removing a flash drive: 2145-CG8 or 2145-CF8

You can remove an installed flash drive from a SAN Volume Controller 2145-CG8 or 2145-CF8 node.

Before you begin

DANGER

Multiple power cords. The product might be equipped with multiple power cords. To remove all hazardous voltages, disconnect all power cords. (L003)

If you are installing a high-speed SAS adapter feature and one or more flash drive features, use the instructions that come with each MES update to install and configure the high-speed SAS adapter and each flash drive.

1. Read the safety information to which Preparing to remove and replace parts refers.
2. Slide the node out on its slide rails to the fully extended position.
   Fast path: You can perform this service procedure with the node in place. Slide the node out six inches to verify that the cover is in place, then return the node to its locked position.

   You can accomplish most service actions when the node is fully extended from the rack on its slide rails. If the location of the node in the rack is too high or too low to work comfortably, you can remove the node from the rack.

3. Optional: If you must remove the node from the rack to work on it, perform the following procedure to turn off the node, remove all cables, and remove the node from the rack:
   1. Follow the procedure in MAP 5350: Powering off a node to verify that hosts will not lose access to data in volumes before you power off the node.
   2. Pull back the cable-management arm if you are working from the rear of the rack, or slide the node out of the rack to the fully extended rail position if you are working from the front.
   3. When the node is completely turned off, remove the cable-retention brackets and disconnect the power cables, as described in Removing the cable-retention bracket.
   4. To make sure that you can replace all cables in the same ports from which they were removed, label the port position of each Fibre Channel and Ethernet cable; then remove all cables from the back of the node.
   5. Remove the node from the rack and place it on a flat, static-protective surface. See Removing a node from a rack.
4. Make sure that the node top cover is in place and fully closed.
   Attention: To avoid damage to the disk drive connectors, make sure that the node cover is in place and fully closed whenever you remove or replace a disk drive.
5. If the service controller ( 1  in Figure 1) is in place, press the release buttons ( 2 ) on each side of the service controller assembly to release the service controller from the node, but do not disconnect the USB service controller cable. Slide the service controller from the node and support it somewhere, if possible, or gently suspend the service controller from the service controller cable.

   •  2  Service-controller release buttons
   •  3  Service controller USB cable
6. Remove the drive from the drive bay:
   1. Slide the orange release latch at the left end of the handle gently to the left to unlock the drive handle.
   2. Rotate the drive handle to the open (unlocked) position, as shown in Figure 2.
   3. Gently slide out the drive assembly along the guide rails until the drive is free of the drive bay.

      •  1  Flash drive
      •  2  Drive handle

      The system error LED and the DASD diagnostics panel LED turn on when a flash drive is removed from a drive bay. The system error LED and the DASD diagnostics panel LED turn off when the flash drive is replaced in the drive bay. If you do not replace the flash drive in the same drive bay, the system error LED and the DASD diagnostics panel LED remain lit. To clear the system error LED and the DASD diagnostics panel LED, turn off the node using the instructions given in MAP 5350: Powering off a node and remove both power cables.

7. If you are not replacing the drive right away, install a drive-bay blank electromagnetic compatibility (EMC) filler assembly into the empty drive bay.

   To make sure that there is adequate system cooling, do not operate the server for more than 2 minutes without either a hard disk drive or a filler panel installed in each bay.

   The electromagnetic interference (EMI) integrity and cooling of the node are protected by having all bays and PCI slots covered or occupied. When you install a drive, save the drive bay blank EMC filler assembly from the drive bay to cover any later removal of the device.

8. If you are removing additional hot-swap flash drives, do so now.
9. If you are replacing drives, replace them now, as described in Replacing a flash drive: 2145-CG8 or 2145-CF8.
10. If you are instructed to return the drive assembly, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
